ABSTRACT
ABSTRACT: This paper focuses on the investigation of the dynamic properties of asphalt concrete using mineral fillers with waste hydrated lime. The ability of hydrated lime to improve the fatigue and rutting resistance of hot mix asphalt (HMA), has led to observed improvements in the field performance of lime-treated HMA pavements, and significant decreases in maintain and repair costs of highways network. The asphalt concretes, made of waste hydrated lime, and ordinary asphalt concrete, evaluated through their fundamental dynamic properties such as fatigue resistance, rutting depth, resilient modulus and permanent deformation. The experimental results showed that improvement the application of waste hydrated lime as mineral filler improves the permanent deformation, stiffness and fatigue endurance of asphalt concrete. It was also determined that the mixtures with waste hydrated lime showed higher resistance against rutting than conventional asphalt concrete.
